Seems I'm having other problem, won't export, but for diffrent reason: takes ages to export, and looks like the operation won't finish, I had to abort it. Oh well, another annoyance! To add to the thread, one of the features advertised for Infinite was " export entire scenes ", so they are definitely not respecting their contract if you can't export content you buy from c3d. Plus, I own Infinte and Pro Studio, and should be able to use my purchases in both apps.
